I'm using 10% omega, and gms does recommend 5 or 10%.

I don't think its the nitro load because if the plane remains level, it'll run wide open perfectly till the tank goes dry. Its when the nose is raised that the trouble starts. It immedietly leans, prodcuing a momentary increase in rpm before it starts to die. If you drop the nose quickly enough, it'll recover and rev back up again.

This same test holds true at reduced throttle positions, but the effect takes a bit longer to occur.

Like I said, its a mystery.
